Exposure to pesticides, ill-health and averting behaviour: costs and determining the relationships

摘要

Purpose - Farmers' exposure to pesticides is high in developing countries. As a result many farmers surfer from ill-health, both short and long term. Deaths are not uncommon. Seeks to address this issue. Design/methodology/approach - Field survey data from Sri Lanka are used to estimate farmers' expenditure on defensive behaviour (DE) and to determine factors that influence DE. The avertive behaviour approach is used to estimate the costs. Tobit regression analysis is used to determine factors that influence DE. Findings - Field survey data show that farmers' expenditures on DE are low. This is inversely related to high incidence of ill health among farmers using pesticides. Originality/value - The results of this study are useful, not only for Sri Lanka, but also for many countries in South Asia, Africa and Latin America in reducing the current high levels of direct exposure to pesticides among farmers and farm workers using hand sprayers. Farmers' exposure to pesticides is a major occupational health hazard in these countries.
